GPA Calculator

Free GPA Calculator

This GPA calculator finds your grade point average on the standard US 4.0 scale. Add a row per course, enter the letter grade (or percentage) and credit hours, and the calculator updates your GPA live as you type. It handles both unweighted 4.0 (A=4, B=3, …) and 4.0 with +/− (A+ and A both = 4.0, A− = 3.7, and so on), plus a percentage mode that maps any score 0–100 to a 4.0 GPA.

How GPA Is Calculated

The formula is straightforward:

GPA = (Σ grade points × credits) ÷ (Σ credits)

Each letter grade has a point value (A = 4, B = 3, etc.). For each course you multiply that value by the credit hours to get "grade points." Sum the grade points across all courses, sum the credits, and divide. A 4-credit A (16 grade points) counts twice as heavily as a 2-credit A (8 grade points) — which is why credit-weighting matters.

How to Use the Calculator

Pick a grade scale that matches your school. Each row represents one course — enter the course name (optional), pick the grade from the dropdown (or type a percentage if using percentage mode), and enter the number of credit hours. Click + Add course to add rows; the × buttons remove them. Your total credits, total grade points, and final GPA update with every change.

US 4.0 Grade Scales

What Counts as a Good GPA?

• 4.0 — perfect, top of the class
• 3.5 – 3.9 — strong, competitive for selective colleges and grad schools
• 3.0 – 3.4 — solid, meets most program requirements
• 2.0 – 2.9 — passing, but may limit some opportunities
• Below 2.0 — most universities require improvement to stay in good standing

Frequently Asked Questions

Does this calculator handle weighted GPA?

The 4.0 scale used here is the unweighted version — every A is 4.0 regardless of class difficulty. High schools that offer weighted GPAs (where honors or AP classes boost grade values, often to 5.0) typically have their own multiplier per class. To compute a weighted GPA, multiply each AP/honors grade by your school's weight before entering it.

What is the percentage mode for?

Many schools, especially outside the US, grade in percentages. The percentage mode maps 0–100 scores to 4.0 GPA points using the standard conversion (93+ = 4.0, 90+ = 3.7, 87+ = 3.3, and so on). This is useful for converting an international transcript to a US-equivalent GPA.

How do I calculate my cumulative GPA?

Add a row per course across all your semesters. The credit-weighted average across every row is your cumulative GPA — which is exactly what this calculator shows in the GPA box.

Are my entered grades saved?

No. Everything runs in your browser and nothing is stored. Refreshing the page clears all rows. If you want to come back to a calculation, screenshot or copy the table before leaving.
